基于Ansys Workbench软件对柔性轴承建立多体接触以及动力学模型,分析了其内外圈在装配及外载荷条件下的应力应变;并基于nCode-Designlife软件,对柔性轴承内外圈进行了疲劳寿命评估。此外,针对影响柔性轴承力学特性的3个因素设计正交试验,分析了其对柔性轴承力学性能的影响。结果表明,内圈的疲劳薄弱位置位于长轴外端面,外圈的疲劳薄弱位置则位于长轴处滚珠与沟道接触区域,且最大径向变形量对内外圈的应力影响显著;在一定范围内减小径向变形并控制滚珠数,有助于减小应力提高寿命。该研究结果为柔性轴承的设计提供了参考。
The multi-body contact model and dynamics model for flexible bearings are established based on the Ansys Workbench software
and the stress and deformation of flexible bearings are analyzed under the conditions of assembly stress and external load. The fatigue life of the inner and outer rings of flexible bearings is analyzed based on the nCode-Designlife software. In addition
orthogonal experiments are designed to explore the relationship between mechanical characteristics and three design parameters of flexible bearings. The results show that the fatigue weak area of the inner ring is located at the outer face of the long shaft
while the outer ring is located at the contact area between the ball and the channel at the long shaft; the maximum radial deformation has a significant effect on the stress of the inner and outer rings. Reducing radial deformation in a certain range and controlling the number of balls are helpful to reduce stress and improve life
which provides reference for the design of flexible bearings.
